The first time you run a program under `use Acme::emcA', the module takes
your source file and makes an mirror image of it at both row- and column-
level. The code continues to work exactly as it did before, but now it looks
like this:
__;use Acme::emcA esu;
;"!dlroW ,olleH" tnirpprint "Hello, World!";
;"!dlroW ,olleH" tnirpprint "Hello, World!";
__;use Acme::emcA esu;
